Abstract:
This work has examines the creation and use of chemical templates for nanocircuit and other nanodevice fabrication. Chemical templating can be useful in attachment, orientation and wiring of molecularly templated circuits. DNA origami provides a suitable method for creating molecularly templated circuits as DNA can be folded into complex shapes and functionalized with active circuit elements, such as semiconducting nanomaterials. Surface attachment of DNA origami structures can be accomplished by hybridization of dangling single-stranded DNA (ssDNA) on the origami structures with complementary surface-bound strands. Chemical templating provides a pathway for placing the patterned surface-bound attachment points needed for surface alignment of the molecular templates. Chemical templates can also be used to connect circuit elements on the surface by selectively metallizing the templates to form local wiring. AFM tip-directed nano-oxidation was selected as the method for patterning to create chemical templates. This project demonstrates new techniques for creating, continuous metallization of, and DNA attachment to nanochemical templates. Selective-continuous metallization of nanochemical templates is needed for wiring of circuit templates. To improve the metallization density and enable the continuous nano-scale metallization of amine-coated surfaces, the treatment of amine-coated surfaces with a plating additive prior to metallization was studied. The additive treatment resulted in a 73% increase in seed material, enabling continuous nano-scale metallization. A new method was developed to create amine nanotemplates by selective attachment of a polymer to surface oxide patterns created by nano-oxidation. The treatment of the templates with the additive enabled a five-fold reduction in feasible width for continuous metallization. Nano-oxidation was also used in the nanometer-scale patterning of a thiol-coated surface. Metallization of the background thiols but not the oxidized patterns resulted in a metal film that was a negative of the patterns. The resulting metal film may be useful for nanometer-scale pattern transfer. DNA-coated gold nanoparticles (AuNPs) were selectively attached to amine templates by an ionic interaction between the template and ssDNA attached to the particles. Only the ssDNA on the bottom of the AuNPs interacted with the template, leaving the top strands free to bind with complementary ssDNA. Attempts to attach origami structures to these particles were only marginally successful, and may have been hindered by the presence of complementary ssDNA in solution but not attached to the origami, or the by the low density of DNA-AuNPs attached to the templates. The formation of patterned binding sites by direct, covalent attachment of ssDNA to chemical templates was also explored. Initial results indicated that ssDNA was chemically bound to the templates and able to selectively bind to complementary strands; however, the observed attachment density was low and further optimization is required. Methods such as these are needed to enable nano-scale, site-specific alignment of nanomaterials.

Abstract:
碩士<br>國立成功大學<br>機械工程學系碩博士班<br>92<br>Traditionally, the delivery of functional particles in liquid media makes good use of capsules, powder and various liquid carriers. Unfortunately, in the traditional ways of delivery, a large portion of functional particles do not arrive at the infected areas. They were decomposed and assimilated by the organs, vessel walls and air bulbs in the way to the infected areas. That is not only inefficient, but also detrimental for bringing in various unexpected side effects to the major system. Thus, how to obtain a better model to allow the delivery process to be more accurately understood and controlled becomes extremely important and urgently needed in many industrial and medical practices.   In view of the need, a new approach by using the nano-particles coating and self-assembled technique is proposed for study. In the functional particles delivery system, three major processes, namely, the self-assembly, the seeding transportion, and the release of nano-particles, are carefully studied. In the self-assembly process, the surface of nano-particles are polarized and then assembled with functional particles to make a complete carrier. In the seeding transportation process, the carrier is injected into the neighborhood of the received zone, and then guided in the fluid flow to the infected areas by using the external magnetic media. In the particles releasing process, the nano-particles were released from the carrier by using either α-ray optical separation or biomedical dissolution techniques. The drug molecules are diffused into the cell membrane of the infected objects with an appropriate control on functional particles supply and seeding effect. In order to model the aforementioned processes, the project employs the theories of DLVO, electromagnetics and hydrodynamics for nanoparticle self-assembly, seeding, releasing and effect tracing. The molecular dynamics is employed to evaluate the process parameters for each of the subprocesses instead of using traditional empirical average values.   The interrelation among these three sub-processes is investigated and an integrated model is proposed. A computerized system is set up to conduct both the numerical and experimental data comparison for signature verification. The results indicate that the modeling procedure proposed in the work is satisfactory.

Abstract:
碩士<br>國立中央大學<br>環境工程研究所<br>93<br>Magnetic seeding aggregation has been developed to remove silica nanoparticles from CMP wastewaters successfully with removal efficiency of turbidity higher than 95 %. With proper treatments, seeded magnetite (Fe3O4) nanoparticles can be reused repeatedly in the magnetic seeding aggregation of CMP wastewaters. In this study, the recovery of magnetite nanoparticles by different types and concentrations of surfactants and removal efficiency of total silicon (e.g. summation of silica nanoparticles and silicate) from CMP wastewaters treated by reused seeding particles were investigated. Experimental results showed that recovery of magnetite nanoparticles was always higher than 99% when silica/magnetite aggregates were treated by any SDS or CTAB concentrations used in this work (0.1 ~ 2 CMC). Though the addition of CTAB limited the separation between silica and magnetite nanoparticles, this improved the reusability of magnetite nanoparticles, which was due to lateral interactions of hydrophobic groups of CTAB molecules adsorbed on the surface of silica nanoparticles. When silica/magnetite aggregates were treated by 0.1 CMC CTAB, the silicon removal ability of magnetite nanoparticles is 1917 mg total Si / 1g magnetite, which is 1497.5% more than those used only once in the magnetic seeding aggregation of CMP wastewaters. However, total silicon removal efficiency of CMP wastewaters was very poor when they were treated by high concentration (2 CMC) of CTAB or SDS. This might be due to the steric repulsions between particles resulted from adsorbed surfactant molecules.

Abstract:
The present work aims at investigating a new challenging use of Aluminum Oxide (Al2O3) nanoparticles to enhance the thermal properties (thermal conductivity, specific heat, and latent heat) of pure paraffin waxes to obtain a new class of Phase Change Materials (PCMs), the so-called nano-PCMs. The nano-PCMs were obtained by seeding 0.5 and 1.0 wt% of Al2O3 nanoparticles in two paraffin waxes having melting temperatures of 45 and 55 °C, respectively. The thermophysical properties such as specific heat, latent heat, and thermal conductivity were then measured to understand the effects of the nanoparticles on the thermal properties of both the solid and liquid PCMs. Furthermore, a numerical comparison between the use of the pure paraffin waxes and the nano-PCMs obtained in a typical electronics passive cooling device was developed and implemented. A numerical model is accomplished to simulate the heat transfer inside the cavity either with PCM or nano-PCM. Numerical simulations were carried out using the ANSYS-Fluent 15.0 code. Results in terms of solid and liquid phase temperatures and melting time were reported and discussed.

Abstract:
Abstract Rapid temperature transients sustained during operation of high voltage electronics can be difficult to manage by relying solely on uniform heat removal mechanisms. Phase Change Materials (PCMs) can be useful as a buffer against these intermittent temperature spikes when integrated into electronic packages. However, their integration poses challenges of both physical and electrical interactions within the package, particularly in high voltage systems. The present study aims to evaluate electrical and thermal properties of nano-enhanced PCMs to inform integration in high voltage systems. The nanocomposites are obtained by seeding 0.0006–0.12 wt% of Gold, Graphene Oxide, and Iron Oxide particles to Sorbitol. Improvements in thermal properties including latent heat as high as 15% are observed; however, this comes at the expense of dielectric strength of the PCM.

Abstract:
Tension metastable fluid states offer unique potential for leap-ahead advancements in radiation detection. Such metastable fluid states can be attained using tailored resonant acoustics to result in acoustic tension metastable fluid detection (ATMFD) systems. ATMFD systems are under development at Purdue University. Radiation detection in ATMFD systems is based on the principle that incident nuclear particles interact with the dynamically tensioned fluid wherein the intermolecular bonds are sufficiently weakened such that even fundamental particles can be detected over eight orders of magnitude in energy with intrinsic efficiencies far above conventional detection systems. In the case of neutron-nuclei interactions the ionized recoil nucleus ejected from the target atom locally deposits its energy, effectively seeding the formation of vapor nuclei that grow from the sub-nano scale to visible scales such that it becomes possible to record the rate and timing of incoming radiation (neutrons, alphas, and photons). Nuclei form preferentially in the direction of incoming radiation. Imploding nuclei then result in shock waves that are readily possible to not only directly hear but also to monitor electronically at various points of the detector using time difference of arrival (TDOA) methods. In conjunction with hyperbolic positioning, the convolution of the resulting spatio-temporal information provides not just the evidence of rate of incident neutron radiation but also on directionality — a unique development in the field of radiation detection. The development of superior intrinsic-efficiency, low-cost, and rugged, ATMFD systems is being accomplished using a judicious combination of experimentation-cum-theoretical modeling. Modeling methodologies include Monte-Carlo based nuclear particle transport using MCNP5, and also complex multi-dimensional electromagneticcum-fluid-structural assessments with COMSOL’s Multi-physics simulation platform. Benchmarking and qualification studies have been conducted with Pu-based neutron-gamma sources with encouraging results. This paper summarizes the modeling-cum-experimental framework along with experimental evidence for the leap-ahead potential of the ATMFD system for transformation impact on the world of radiation detection.

Abstract:
The field of tissue engineering and regenerative medicine is an interdisciplinary field that applies the principles of engineering and life sciences toward the development of biological substitutes that restore, maintain, or improve tissue function or a whole organ. The process involves seeding cells onto biocompatible scaffolds that temporarily act as a supporting structure for cells to attach and grow. Scaffolds for tissue regeneration must present a viable microenvironment for the living cells to adhere, proliferate, and exhibit the necessary tissue function. Electrospinning is an emerging area where polymeric fibers can be fabricated in the micro-nano scale. The flexibility of this process allows for including a wide array of synthetic and natural biocompatible polymers in the scaffold composition, inclusion of bioactive molecules (e.g. DNA, proteins) for enhancing therapeutic applications, and ability to control material and mechanical properties via the electrospinning process — all advantageous parameters that contribute to the promise of utilizing electrospun scaffolds in tissue repair. Biocompatible materials, such as polycaprolactone (PCL), have been used extensively to fabricate scaffolds using electrospinning technique, to study cell compatibility and to evaluate cell functionality for nerve tissue engineering applications. The objective of this study is to quantify the effects of the addition of valproic acid to PCL nanofiber scaffolds created through the electrospinning process with regards to cell proliferation. Valproic acid is a commonly used therapeutic drug for the treatment of epilepsy and bipolar disorder. To determine the effects of the presence of valproic acid (VA), Wharton’s jelly mesenchymal stem cells (MSC) are seeded to the two scaffolds. Wharton’s jelly MSC are multipotent adult stem cells present in the umbilical cord and drawn from their matrix [1,2,3]. These stem cells have renowned ability for use in cell therapy and organ regeneration. This study tests the hypothesis that the presence of valproic acid in PCL nanofiber scaffolds will enhance cell proliferation. Structural and morphological characterization of the scaffolds is also carried out. Fiber diameter and tensile properties of the scaffolds with and without valproic acid are also observed. Such studies will enable us to understand the effects of drugs such as valproic acid on stem cells and will aid in designing scaffolds for applications in nerve regeneration.
